NATHAN D. MOREY, OF SARATOGA SPRINGS, NEW YORK.

CARBURETOR.

SPECIFICATION forming part of Letters Patent No. 247,390, datedSeptember 20, 1881. Application filed June 17, 1881. (No model.)

To all whom it may concern Be it known that I, NATHAN D. MOREY, ofSaratoga Springs, in the county of Saratoga and State of New York, haveinvented certain new and useful Improvements in Carburetors and I dohereby declare that the following is a full, clear, and exactdescription thereof, reference being had to the accompanying drawings,and to the letters of reference marked thereon, which form part of thisspecification.

This invention relates to certain improvements in carburetors; and ithas for its objects to provide an apparatus which may be of anycapacity, and by means of which gas or air may be thoroughly and safelycharged with hydrocarbon vapors, as more fully hereinafter specified.

The invention relates particularly to that class of carburetors in whichthe hydrocarbon fluid is supplied to the carbureting-vessel from asuitable tank and distributed over carburetin g-surfaces therein, and itis designed to more eftectuallydistributethe carbureting-fluid over suchcarbnreting-snrfaces.

These objects I attain bythe apparatus illustrated in the accompanyingdrawings, in which- Figure 1 represents a side elevation of thecarbureting-chamber; Fig. 2,21. top view of the same; Fig. 3, a verticalsectional view of the carburetiug-chamber and an inclosing water vesselor tank, and Fig. 4 a detached view ofthe foraminous chambershereinafter described.

The letterAindicates the carbureting-chamber, which is constructed ofmetal or other suitable material, rectangular in horizontalsection, andhaving its walls tapering slightly from the top to the bottom. The saidchamber is located in a tank or vessel, 13, which contains watersufficient to cover the chamber. The upper edge of thecarbureting-chamber is provided with a flange, G, to which a removabletop is secured by means of bolts D, a packing of rubber or othersuitable material being interposed between the flange and the top tomake a gas-tight joint.

TheletterE indicates the gas-induction pipe, extending down through thetop of chamber at one side, and then across it horizontally in the upperpart, as shown in Fig. 3. The chamber is provided just above thehorizontal portion of the pipe E with a foraminous dia phragm, F,dividing said chamber into an upper and a lower compartment.

The letter G indicates a vent, H a fillingtube for charging theapparatus with liquid hydrocarbon, and I the eduction-pipe through whichthe carbureted gas leaves the apparatus. The lower eompartmentisprovided with aseries of foraminous reservoir-chambers, K, with spaces Lbetween them. The said spaces are packed with prepared wicking or otherabsorbent material, which is held in place by the foraminous diaphragmabove mentioned. The horizontal portion of the gas-induction pipe passesthrough the upper parts of the reservoir-chambers and communicates withthem by means of apertures M, so that the gas may readily pass throughsaid chambers and the packing in the intervening spaces, and thus becomethoroughly charged with hydrocarbon vapor.

The letter N indicates a gage by means of which the height of the liquidin the chamber may be observed, and 1 an overflow-tube, through whichany excess of liquid may pass off in order to prevent the apparatus frombein g filled above the proper level.

The tube H, at its lower end,is provided with a rose or sprinkler, R, bymeans of which the hydrocarbon is distributed in filling.

It will be observed that the apparatus, as above constructed, requiresno outside reservoir to supply it with liquid hydrocarbon, and

hence is unattended by the danger resulting from such-reservoirs, andcan be made of dimensions so small as to be employed in connection withan ordinary drop-light, or can be made of a capacity sufficient tosupply any number of lights. As the topis removable, the chamber may bereadily cleaned when required.

I am aware that carburetors have heretofore been constructed in whichthe liquid hydrocarbon has been supplied and passed down throughabsorbent packing in the carburetor, and this I do not desire to claim.

Having fully described my invention, what I claim, and desire to secureby Letters Patent, is-

1. The combination, with the carburetingchamber, of the inlet-pipe E,extending down through thesame,andtheforaminous reservoir.

IOC

chamber K, the said inlet-pipe passing through these chambers andcommunicating therewith by means of the apertures M as shown anddescribed.

2. The combination, with the carbureting chamber, of the inlet-pipe E,extending down through the top and then horizontally across the same,the foraminous reservoirs, through which said pipe passes andcommunicates, and

the foraminous diaphragm F, located above IO said chamber, as specified.

In testimony that I claim the foregoing as my own invention I aflix mysignature in presence of two witnesses.
